There’s actually quite a bit of setup required. Reinstall upgraded scenery, aircraft, airports and more. Re-calibrate the joystick and reassign keys to my liking. But mine is nothing compared to some users who have lots of add-ons. I needed to get Little Navmap working again, a great free plugin, that among many other things, allows you to track your flight on a map. I had just downloaded the newest version recently but it didn’t work (some library issues) on my older Linux Mint, but does on the latest Linux Mint 20.1. A plugin was also required.
